KYOWA ELECTRONIC INSTRUMENTS CO., LTD. COMPACT RECORDER EDS-400A Compact Dynamic Strain Recorder Entering the scene in advanced measurement of strain, vibration, pressure, load, etc. New www.kyowa-ei.co.jp
Signal conditioners and 16-bit A-D converters are incorporated, 4 channels each, into a compact package to perform advanced measurement in limited spaces. The 4-channel EDS-400A is equipped with signal conditioners and 16-bit A-D converters to digitally record dynamic strain and voltage signals at high speeds. It can be set to desired recording conditions through either a PC connected to the LAN interface or a CF memory card inserted into the slot. The recorder amplifies and digitizes input signals, and then saves the results in the CF memory card. The PC, if connected to the LAN interface, enables monitoring of waveforms of the data being recorded. The acquired data can be transferred to the PC either on-line via the LAN interface or off-line via the CF memory card. The accessory software enables the PC to graphically display the data while the optional DAS-100A or NI DIAdem analysis software enables data analysis in various modes on the PC. Data is saved in CF card. LAN interface enables PC to control EDS-400A and to collect data.
